I assume you know how to find the enthalpy of a saturated liquid- vapour mixture. If heat is transferred at constant pressure, ie. at saturation pressure, just add the amount of heat to the initial enthalpy value, to get to the final enthalpy value. If heat addition is not isobaric, but...

Hey everyone! I am working on improving natural draft counter flow cooling tower efficiency as my final year B.E. project. I came across a research paper that said that at transverse cross section of the tower, above drift eliminators, the air velocity decreases from the periphery to the...

Cengel: for both fluid mechanics and thermodynamics

P. S. I have discussed this concern with the seniors too, but so far we haven't come to a decision regarding this.

Hey everyone! I am on a 15 day industrial training in an organization, which is involved in designing and fabricating dairy and pharmaceutical process components. Right now, i m in component engg. department, where the design and documentation of dairy components takes place. Prsently i am...

I think if you are interested purely in aerospace, then you should go with a course in aerospace only. Mechanical engineering is way general for the syllabus of the entrance test you have put up here. I don't think a course in mechanical engineering would train you well specifically for...

With mechanical engineering, you will understand a whole lot of theories and principles, that you may as well apply to design of cars and their parts. With automobile engineering, you will probably learn these same principles, but apply them only to cars, engines etc. during your entire period...

I agree with the posts above. But remember, "programming" is different from the daily work we do on computers. To be a good computer engineer, you should be able to apply logic (basic common sense that we most of the time take for granted) well. It is like making a computer understand what you...

Actually i was suggested this project by a person who is a manufacturer of strainers. I will speak with him regarding the possible developments in this field. Thanks a lot Sir! You really boosted my confidence.

The only problem i found out so far from most strainers is their cleaning. However there are already online strainers, the ones that can be cleaned while under operation, and some automatically cleaning strainers as well. I am doubtful if this would be an area huge enough to explore.

The mechanics of fluids is different from that of rigid bodies, even though both are governed by Newton's laws. The approach to analyzing "flow" is different as well. So your weakness in rigid body dynamics will not affect this course at all. However take this tip: Fluid Dynamics involves study...

I really need huge help on this. I have been suggested analyzing industrial stariners as a final year mechanical engg. project. However my project would require finding out existing problem/s in the element under analyses and I am not able to find any single problem (i.e. huge enough for a...

If I place a bicycle wheel on the floor, it flips over and falls down... Same is with the toy top. But when the wheel or the top spin, they remain stable. Can someone please explain the physics behind this?

Ok.. anyway for most metals (the ones that contract on cooling) the bore diameter will decrease during the shrinkage of casting, right?

So this is exactly what would happen during the cooling of a similar casting, after it has solidified?
